Naysayers are those who continually discourage you from trying new experiments and coming up with new ideas and inventions. Naysayers may even be loved ones or family.

Naysayers must be ignored since the most excellent ideas are first ridiculed by the vast populations.

"Ideas will first be ridiculed, then violently opposed, and finally accepted as self-evident"
--A. Schopenhauer 1788-1860

Abandon Orthodox Thinking and Tradition

When a man discovered the Moon was not flat and described how planets actually worked, and that planets and moons out there were round.. he was persecuted by the Catholic church for propagating such nonsense. Of course, the man was right about the planets, stars, and moons, and the naysayers didn't give him any chance.

Lessons From Magick

Even the Magick expert Crowley, said:

"...one must eliminate from oneself every element alien or hostile to success, and develop those parts of oneself which are specially needed to control the aforesaid conditions..."

The Ultimatum

Unfortunately, this may even mean not associating with certain people if they are restricting your path in life. It requires being very selectively social (rather than say anti-social).

Try Identify Problem People

Identify the naysayers. If they are just questioning you and helping you by pushing you harder - this is fine. But if they are getting in your way and detouring you by making you feel awkward for trying new experiments and ideas, you must rid them or decrease your time with them significantly.

Different forms of Nervousness and Anxiety

Be especially careful, if you feel negatively nervous around someone that you must talk to each day. You should not feel constantly negatively nervous for being experimental and creative. The negative nervous signs are strong warnings that you must rid the person from your life (being nervous with newly met people is not what I'm talking about - I'm talking about being nervous bringing up conversation with people you've known for quite a while).

If you feel happy (positively) nervous (such as I can't wait to tell this person and find out what they think) then this is perfectly fine.
